Can the raw material tank truck be sampled first before entering the plant and being weighed?
Thread Content
Under normal circumstances, the raw material tank truck should first enter the plant, be weighed, come to a stop, and then a sample be taken. Our facility is relatively small. When there are other tank trucks carrying the same type of raw material on site, it’s inconvenient to have this particular tank truck parked inside the plant. Is it permissible for it to park first in an open area outside the plant? Once the samples have been taken, the analysis results are obtained and found to be satisfactory, and provided that there are no other tank trucks at the unloading stations and no tank trucks are exiting via the internal roads, can this tank truck then be allowed to enter the plant for weighing? This could lead to measurement disputes – whose responsibility is it to sample those materials, and who will pay for it?
Sure, that’s how we do it – as long as sampling does not affect traffic, the environment, or safety. Does sampling really affect measurement? How many samples do you need to take? Since it’s a filling vehicle, it should be measured in tons, right? How much can a single container of raw material be worth—tens of millions? I’m a bit confused.
From a system management perspective, the quality and weight of raw materials are not incorporated into a closed-loop management process; they are uncontrollable and constitute non-conformities. Case: Monitoring in the control room of the finished product filling station at Factory X revealed that after the tank truck arrived at the factory, the driver took out two plastic buckets from the truck and poured the liquid into the drainage ditch. According to the driver, he would hide two buckets of liquid in the truck during weighing, then find an opportunity to pour it out, thereby being able to carry more liquid material each time and thus defrauding the company of its interests.
I see that in your example it was only possible to detect the issue through monitoring; so if I install cameras, will that solve the problem? After all, vehicles parked outside the area are definitely parked in front of the entrance, and cameras would be very useful for that purpose. Are there any specific laws and regulations that strictly prohibit raw material tank trucks from stopping outside the company’s perimeter (near the perimeter, not thousands of kilometers away from it)?
It is precisely because abnormal behavior was detected through monitoring that the vulnerability was contained. Still from the perspective of system management, all management actions and production activities at your factory can only start from the moment something enters the factory premises; how can they extend to social regulatory agencies (such as transportation and public security departments)? Just think: if an accident occurs with a raw material tank truck parked outside the company’s fence, whose responsibility is it? Is it the traffic police who will handle it, or is your factory responsible? “It’s inconvenient to have this raw material tank truck parked inside the factory premises. Is it possible to allow it to park first on an open area outside the factory? Once the samples have been taken, the analysis results are obtained, and everything is found to be satisfactory—and only when there are no other trucks at the unloading bays and no tank trucks are exiting via the internal roads—can this tank truck be allowed into the factory? During this waiting period, who might tamper with or substitute the raw materials in the tank truck? How is quality ensured?
Don’t ask whether there are specific laws and regulations – even street-side shops that occupy road space are subject to regulation by urban management, let alone when the sampling of chemical materials is carried out on public roads (or parking lots) outside the factory.
The car can be parked outside; in theory it’s possible, but there are certain risks involved
Wasn’t the location for tank trucks considered when the plant was built?
